The wills of Maryland's most affluent shed light on their wealth and, many times, their hobbies. They do not always show the full picture, though. In many cases, assets are steered into trusts that do not require public disclosure.

Hackerman, the longtime chief executive of contracting behemoth Whiting-Turner who died last month, collected maps for more than 15 years.

His map collection included about 60 from between the 16th and mid-19th centuries. They were featured in a 1998 Maryland Historical Society fine art exhibit called "Mapping Maryland: The Willard Hackerman Collection."

His will discloses $50 million in assets and $2 million in real estate. A breakdown of what those assets are — and whether they include the map and car collections — has not been filed. But the majority of Hackerman's wealth went into a revocable trust, which doesn't require a public inventory.

Clancy, the best-selling Baltimore writer whose military novels garnered worldwide acclaim, included properties in Calvert County and Martha's Vineyard in his will. The author, who died last year, didn't have an antique car collection, but his 2001 Ford F-150 and 1993 Cadillac Allante convertible were both in good condition, according to his will.

A document filed with Clancy's will says he owned personal and real property worth $50 million, but the documents lay out specific assets that represent only a small part of that total.

Outside of any trusts of his own, which would not be publicly available, Clancy's corporate holdings were listed at more than $979,000. He had another $79,000 in bank accounts, savings and loans and cash. At the time of his death, his estate, which went to his wife, was worth more than $1.07 million.

Donovan, a Hall of Fame Baltimore Colts defensive tackle who died in August, owned and operated his family's liquor stores and Valley Country Club in Towson after his 12-year football career.

He directed his stock in the club, like most of his assets, into a trust that does not require a disclosure of its value. A full inventory of Donovan's assets had not been filed with the Baltimore County Register of Wills as of last month.

Philanthropist Willard Hackerman, who transformed a small construction firm into a national giant with $5 billion in annual billings and was instrumental in erecting Maryland landmarks such as Harborplace, died Monday of unknown causes at Johns Hopkins Hospital. He was 95.

After shooting down the state's request for disaster aid for the second time last week, the Federal Emergency Management Agency said Maryland could recover costs associated with rioting that broke out after the death of Freddie Gray in other ways.

In July, Baltimore marked a gruesome milestone, recording 45 homicides — the highest monthly tally in more than four decades. Here are some other statistics on city homicides, according to data since 1970.
